In a recent project for a client I was tasked with modifying an existing excel spreadsheet to add data from a query. Being familiar with Java and ColdFusion I assumed this would be a pretty trivial exercise. Read the existing file, get the sheet and then write the data, but I ran into an issue where adding rows using shiftRows didn’t make them writable and/or visible to apache poi. I realized I needed to literally add the rows and the columns to the excel spreadsheet to be able to change the values. Not a big deal code-wise and also really fast to complete, but frustrating to figure out.
